Background technology
[0004] knownly for a long time contain recombinase system such as intestinal bacteria and zymic microorganism, it realizes homologous recombination not needing to provide under the condition of exogenous enzyme such as ligase enzyme.For example, Oliner, J.D., et al, Nucleic Acids Res. (1993) 21:5192-5197 has described the method for clone PCR products, and this method is by the identical end sequence of sequence with linearizing carrier two ends is provided to them.Product and carrier DNA cotransfection in coli strain JC8679, are carried out recombinating in the body to carrier and PCR product.By identifying the bacterium colony that contains recombinant plasmid with the hybridization of diagnostic DNA.The author has proposed the prioritization scheme with this method clone gene group PCR product in intestinal bacteria.
[0005] nearest, Zhang, Y., et al, Nature Genetics (1998) 20:123-128 has described similar methods, thinks that this method has increased the size of the DNA that can pass through this method clone.
[0006] U.S. applies for that openly 2003/0044820 has described with PCR nucleic acid fragment is cloned into method in the carrier, and this method has adopted the linking sequence, and described sequence can contain functional element, as promotor, terminator, selective marker etc.By the linearizing carrier of pcr amplification, rather than prepare linearizing carrier by routine clone and digestion subsequently.This has increased provides the advantage of additional sequences for linearizing carrier, and described sequence can be mated the connection portion of the nucleic acid of pcr amplification.The unique system that is used to select have the bacterium colony of recombinant plasmid has also been described.
[0007] nearest, Parrish, J., et at, J.Proteome Res. (2004) 3:582-586 have described the parameter that influences the cloning efficiency that adopts the routine techniques of recombinating in intestinal bacteria.In this work, the frame that has increased and in campylobacter jejuni, identified, and the linearized vector in the insertion intestinal bacteria.Separate each bacterium colony, the clone is checked order.Adopted the amplification right to the primer of the total length ORF of 1,685 kind of gene of genome sequence prediction, wherein determined should biology described genome sequence.1,346 kind of PCR product is visible on gel, and 75% in these genes provide to have and contain the bacterium colony that inserts segmental carrier.
[0008] also known cell except that intestinal bacteria with recombinase function.For example, Ma, H., Kunes, S., Schatz, PJ.and Botstein, D., Gene (1987) 58:201-216 has shown that Saccharomyces cerevisiae can carry out this reorganization.
[0009] aforementioned every kind of method all needs to separate the mono-clonal that is used to produce every kind of target protein, and this is the step that is difficult to be suitable for high throughput processes, and may cause the separation of mutant rather than intact proteins.Therefore, preceding method all can not easily provide great majority or a large amount of albumen of all complete genome groups, the i.e. Sheng Wu intact proteins group of for example representing infectious agent (infectious agent) in a large number.Therefore, still need to make it possible to prepare the high-throughput scheme of described protein groups array, can analyze this array, obtain various interactions and characteristic.
[0010] one of purposes of described array is to identify the immunoreactive protein that produces by by infectious biological, as a step of anti-this biological vaccine of exploitation.A lot of forms have been adopted in the effort of the described antigenic protein in the evaluation infectious agent.In hydropathic profile, analyze albumen, for example, determined and to expose, therefore can contact immune zone.Perhaps, (as United States Patent (USP) 6,620, the description in 412 and 6,451,309) detected in 400 kinds of monoclonal antibodies and the ability of virus, detected the ability that their protection mouse avoid attacking then.Thus the antibody of Jian Dinging associate in they immunoreactive albumen.Many such albumen have been identified.
[0011] U. S. application 2003/0082579 has been described by the protein arrays that derives from infectious biological with at least a antibody screening that exists in the immune serum and has been identified antigenic method, and described immune serum carries out stimulation oversaturation with this biology or biological part.By pcr amplification coding property DNA, carry out second then and take turns pcr amplification to import transcriptional control sequence; Take turns the external albumen that is translated as of product with second then, obtained the albumen in the array.But clearly, if attempt in the high-throughput mode, the method for the acquisition protein arrays of description has produced albumen in shortage.
[0012] therefore, these methods have proved passes through to screen albumen or the proteic part of the albumen of infectious agent with the evaluation induce immune response, can find useful antigenic protein in vaccine and diagnosis are developed.But because they need be at every kind of albumen sepn mono-clonal, they can not be provided for identifying the antigenic high throughput method of characteristic of infectious agent, and described characteristic antigen has been represented the possible antigenic protein or the four corner of peptide moiety.Need described fast method to come rapid answer, with vaccine or the diagnostic test of exploitation at new infectious agent biological example weapon.By allowing synthetic albumen/peptide array of representing the intact proteins group substantially, and, the invention provides the chance of most possible material standed for that rapid evaluation is used for the stimulant of diagnostic test, vaccine and T cellular immunization by providing the means that realize it with practical ways that can automatization.

Implement pattern of the present invention
[0053] one embodiment of the invention provide the high throughput method of the array of the albumen that obtains representative encoded protein and/or peptide in the genome of infectious agent and/or peptide, make it possible to test the ability that this array causes body fluid and/or cellullar immunologic response.Proteic method in the preparation array is applicable to the albumen that generally prepares any source.Particularly, inherent high-throughput advantage is applicable to and provides from the albumen of infectious agent and the repertoire of peptide in this method.This method also can be used to provide multiple protein and/or the peptide by any nucleic acid encoding of known array, makes the part or the insertion fragment of each amplification to be offered the plasmid that can duplicate in containing the microorganism of recombinase.The described proteic method of preparation of the present invention is the DNA of its employing from the mixture extraction of microorganism with the difference of the method that adopted in the past, and the mixture of described microorganism is by cultivating transformation mixture rather than obtaining by separating single clone.This is favourable, because clone's separation causes obtaining the proteic natural form of mutant rather than needs usually.In addition, at screening stage, method of the present invention can adopt the not purified form available from the vector encoded of these mixtures and expressed proteins.Therefore, method of the present invention has significantly been simplified the automatization of general procedure, and has adopted high throughput processes.
[0054] adopt method of the present invention, can identify the specific protein from vaccinia virus, it will be effective vaccine.This is very significant, because the use of attenuated virus brings disadvantageous side effect sometimes.Preferably utilize single albumen or proteic definite mixture, rather than the complicated infectious agent of attenuation form.At present, for example, use hepatitis B virus surface antigen to realize this point.
[0055] as indicated above, method of the present invention is applicable to the nucleic acid (wherein known relevant nucleotide sequence) of encode generally multiple protein and peptide, the feasible segmental amplification of insertion that can need with suitable primer realization.As described in the US2003/0082579 and US2003/0044820 that are hereby incorporated by, the primer of design can comprise that the homologous recombination to needs provides the linking sequence of linearized vector.The primer self and/or the linearizing carrier that extend can provide suitable control sequence subsequently, as promotor and terminator, to realize expression and " mark ", as histidine mark, FLAG mark etc., to allow the reinforcement that combines with suitable solid surface, or if desired, allow the purifying of expressed proteins.Usually, also by the linearizing carrier of pcr amplification, rather than adopt more conventional vector digestion method, described ordinary method can obtain to contain and insert segmental carrier.
[0056] in group method of the present invention, coding multiple protein or peptide, and the known nucleic acid molecule of nucleotide sequence as the infectious agent genome, are used as substrate.With increase the separately fragment of (promptly in single reaction mixture) each coding protein of interest or peptide of PCR or other amplification technique, wherein adopt and contain and terminal portions complementary sequence of encoding sequence and can coded markings and/or the adapter of the sequence expressed of control, but, its in anything part all with linearization plasmid on the sequence homology that provides.Then, the fragment of amplification separately and linearizing plasmid co-transfection in the microorganism that contains recombinase, are recombinated in the body carrying out.The biology that contains recombinase can be that for example, yeast maybe can be chemoreception attitude intestinal bacteria (or secondly ideal is electroporation competence intestinal bacteria).Suitable chemoreception attitude intestinal bacteria comprise bacterial strain JC8679, TB1, DH5 α, HB101, JM101, JM109 and LE392.Saccharomyces cerevisiae is the yeast that especially effectively contains recombinase.
[0057] ratio of DNA and cell can be up to 1,000,000 cells of 100ng/ in the transfection reaction; But the ratio that is low to moderate 1-10ng, 5-10ng, 1-5ng or 1,000,000 cells of 1-3ng/ also can be used.Usually need provide linearizing plasmid, the ideal nucleotide sequence is about 1: 1 mol ratio, but also can use 5: 1 to 10: 1 to 100: 1 ratio, also can be to use 1: 5 to 1: 10 to 1: 100 ratio.
[0058] handles cell with the insertion fragment of amplification thus, on suitable medium, cultivate the linearized vector of amplification, usually overnight incubation.Obtained the mixture of cell, great majority contain the recombinant vectors of needs, and described carrier has the fragment of the amplification of the required nucleotide sequence that inserts with correct direction.(guaranteeing directivity with the homology part of coupling linearization plasmid) by the design primer.Directly obtain plasmid DNA, rather than separate single colony,, and help obtaining mutant because separate the segmental risk of insertion that single colony has the loss needs from culture harvested cell and extraction.By proper host cell is arrived in the DNA transfection, perhaps, in external translating system, make plasmid mixture transcribe/translate then usually in order to reach high-throughput.Described external translating system is commercially available, and the method for using them is well known to a person skilled in the art.Then, can be directly with the albumen that obtains or peptide point sample on solid support, described upholder can be albumen and the array of peptide, the hole of described surface such as microtiter plate or the sectional nitrocellulose in any suitable surface preparation.If desired, purifying protein perhaps adopts from primer or plasmid-encoded mark purifying protein to albumen by means commonly known in the art, perhaps, can directly use and transcribe/translate mixture, and not be further purified albumen, so that provide albumen or peptide to solid support.By the purifying of this method production or the albumen of basic purifying is an aspect of of the present present invention.These albumen or peptide can be naturally occurring peptides, or comprise one or more interpolations, the modified forms of epi-position mark as described further below.When albumen is attached to upholder, the corresponding part of the mark on albumen or the peptide is provided for solid support self.
[0059] in order to obtain proteic array, the step that the ORF that needs number or its part are carried out aforementioned order.If for any screening of carrying out on array, possible material standed for is known, only obtaining relatively small number target protein or peptide may be favourable as the member of albumen/peptide array.But, can change multiple nucleotide sequence into albumen or peptide; As many as 50,100,500,1,000 or more.For example, if adopt the genome of infectious agent, or any procaryotic genome, array can comprise at least 10%, 20%, 50%, 75%, 90%, 95% or 100% expressed proteins and peptide.The array that obtains can be represented biological complete substantially protein groups, promptly at least about 98% protein groups or its part only, maybe can represent the proteic single peptide moiety in the protein groups, the combination of full-length proteins and partial sequence.
[0060] in order to promote the preparation of peptide or proteic array, maybe advantageously with interested peptide or albumen and the fusion of small peptide mark, the common length of described mark is 6-20 amino acid, and it is incorporated into the particular functional group.Then, described bonding mark can be used for purifying protein or with proteopexy in test surfaces, or detect proteic existence.The described bonding mark of being made up of short aminoacid sequence is known, so-called epi-position mark.For example, by suitable nucleotide sequence being mixed the adapter that is used for genomic nucleic acids is inserted expression plasmid, can (10 amino acid whose fragments of people's proto-oncogene myc EQKLISEEDL) be blended in peptide or the albumen that will express with hemagglutinin (HA) epi-position mark (as human influenza virus's hemagglutinin YPYDVPDYA) or c-Myc epi-position mark.Then, can use the antibody test of c-Myc, HA or other epi-position mark or the peptide of localization and expression.
[0061] similarly, polyhistidine tag can be used as the epi-position mark, and can mix in the expressed proteins by the appropriate designs of adapter, and described adapter is used for genomic nucleic acids is inserted the carrier that is used for expressing protein.Polyhistidyl epi-position mark can comprise 3-12 histidine residues continuously, usually 6-10 continuous histidine residues.Described polyhistidine tag is with specificity and combining closely in nickel surface; Thus, contain the peptide of expression of described mark or albumen and will combine closely in the surface of nickel bead, nickel bag quilt or comprise nickel or nickel salt or complex compound, as the affinity column of nitrilotriacetic acid(NTA) nickel (Ni-NTA).Therefore, by with nickel or nickel salt or complex compound bag by each hole, then the solution of every kind of albumen or peptide is placed the hole of described nickel bag quilt, and makes proteopexy in the surface, contain the albumen of polyhistidine tag or the array of peptide with 96 well format productions.Similarly,, or, described albumen can be attached to pearl, be used for showing easily by be coated with the pearl of other material with nickel or nickel salt or complex compound by the preparation nickel bead.In one embodiment, genomic albumen is carried out mark, make it be attached to the nickel bead of 1um with the polyhistidine tag that comprises at least 6 continuous histidine residues; Then these pearls are used to measure the immunne response of T cell, as the hereinafter description of embodiment 9.
When [0062] needing, also can connect two kinds of different marks: the nucleotide sequence of first mark of encoding, it can be included near the 5 ' end of the nucleic acid that inserts plasmid, so that N-terminal linkage flag in expressed proteins, nucleotide sequence with coding second mark, it can be included near the 3 ' end of the nucleic acid that inserts plasmid, so that in the C-terminal linkage flag of expressed proteins.These marks can be identical, to guarantee being covered identification under the therefore unreachable situation when end; Or they may be different, to guarantee to use two kinds of different catching or detection method.Be used to detect, other mark of location or purifying also can be connected in genome albumen as required.Described mark comprises glutathione-S-transferase (GST), biotinylation signal, green fluorescent protein (GFP) etc., can mix each described mark by means commonly known in the art.

[0126] for the immunodotting trace, the full RTS of 0.3 μ l volume is reacted artificial point sample on nitrocellulose filter, dry, then with the sealing of 5% skim-milk among the TBS-Tween.Survey trace with VIG, in the sealing damping fluid that contains or do not contain 10% intestinal bacteria lysate, be diluted to 1/1,000.Three crowdes of different VIG have been adopted: lot number 1730204 (56mg/ml), lot number 1730208 (53mg/ml) and lot number 1730302 (56mg/ml).Detect people's antibody by incubation in the anti-people IgA+IgG+IgM of alkaline phosphatase link coupled goat (H+L) second antibody (JacksonImmunoResearch) and with nitro-BT photographic developer observation.Routinely, also use monoclonal anti polyhistidyl (clone His-1; Sigma H-1029) and mono-clonal rat anti hemagglutinin (clone 3F10; Roche 1867423) antibody, use AP link coupled goat anti-mouse IgG (H+L) (BioRad) or the mouse IgG of the goat Chinese People's Anti-Japanese Military and Political College (H+L) second antibody (Jackson ImmunoResearch) dyeing then respectively, to confirm existing of recombinant protein.
[0127] sets up in-vitro transcription/translation reaction with 25 μ l scales, also set up and adopted the control reaction of non-recombinant expression plasmid, so that the contrast that exists as bacillus coli antigen as template.After 5 hours building-up reactionss finish, immediately with the albumen point sample or be arranged on the nitrocellulose matrix, and be not further purified, or remain on and be no more than 12 hours under 4 ℃, then trace.Under non-sex change condition, carry out the point sample of RTS reaction, and be not further purified (Fig. 7).Find that colibacillary antibody all is high titre in human serum and VIG, unless and be closed, then cause covering the high background dyeing of any antigen-specific reaction.This is by to remove Chinese People's Anti-Japanese Military and Political College enterobacteria reactive or overcome with blocking antibody by introduce 10% intestinal bacteria lysate in serum or VIG with being fixed on e. coli protein on the nitrocellulose filter.In fact, our effect of finding to adsorb immunoblotting with block to compare and have nothing different (data not shown goes out) by adding lysate.Therefore, a kind of technology in back is used as the painted ordinary method of blocking-up intestinal bacteria background, and this is because it allows to use (typical case is each microarray 2-3 μ l) with the consistency of high flux screening and the economy of human serum.When introducing lysate, the intensity of spot significantly reduces in the control reaction, causes at the proteic stronger signal to noise ratio of antigenicity vaccinia virus.Should notice that also VIG is a conformation dependent to the reactivity of A11L.In Western blot, discern this specific antigen easily, but nonrecognition in the non-denatured form of Dot blot.

Microarray
[0128] Fig. 8 shows the flight microarray that adopts identical RTS reaction, and described RTS reaction is used for the immunodotting trace that Fig. 7 describes.For microarray, at first 15 μ l volumes are transferred in 384 orifice plates, 1,600xg is centrifugal, to be settled out all throw outs, under situation about not being further purified, use Omni Grid 100 microarray trace instrument (Gene Machines) with the FAST of supernatant liquor trace to nitrocellulose bag quilt TMSlide glass (Schleicher﹠amp; SchuellBioscience) on.For all dyeing, at first slide glass is sealed damping fluid (Schleicher﹠amp in protein arrays; Schuell) sealing is 1 hour in, uses first and second antibody identical with Dot blot (adopting the Cy3 link coupled second antibody available from Jackson) dyeing, scans in laser cofocal scanner.(GSI Lumonics Inc) carries out quantitatively fluorescence intensity with QuantArray software.When adopting full RTS to react on Dot blot and array, VIG has Chinese People's Anti-Japanese Military and Political College's enterobacteria antibody of any antigen-specific reaction of covering of high titre.This is to overcome by the immunoblotting that makes VIG absorption intestinal bacteria lysate or by the intestinal bacteria lysate is added VIG.In preceding a kind of method, intestinal bacteria are dissolved in the SDS PAGE sample buffer, on the preparation gel, differentiate lysate, transfer to Optitran nitrocellulose filter (Schleicher﹠amp then; Schuell) on.Then trace is cut into little (5 * 5mm) sheets, and in 5% skim-milk the sealing 1 hour.Wash described small pieces then, be placed in advance with the sealing damping fluid and be diluted among 1/1000 the VIG, continued to stir down incubation 1 hour.1 liter of intestinal bacteria (DH5) culture stationary phase from be resuspended in 25ml TBS-Tween prepares the intestinal bacteria lysate, with the probe sonication of 2cm diameter.Branch things such as 1ml are stored down at-80 ℃.
[0129] under the condition of purifying not with in-vitro transcription/translation reaction trace to the slide glass of nitrocellulose bag quilt, survey with the VIG that contains and do not contain 10% intestinal bacteria lysate.The contrast spot is formed as the RTS reaction of carrier by having non-recombinant expression plasmid.By calculating the mean value and the standard deviation of the fluorescence intensity that contrasts spot, set up " by value " (dyeing that is higher than it can be thought male) arbitrarily.As can be seen, when having lysate among the VIG, also detected detected same protein in the immunodotting trace by microarray.Fluorescence link coupled second antibody provides than using the observed strength of signal widely of immunodotting trace.As if in addition, microarray has also produced the sensitivity higher than immunodotting trace, because we have observed certain situation, wherein detected albumen is lower than the detection threshold (not shown) of Dot blot in array.
[0130] Fig. 9 has shown 96 vaccination seedling diseases poison and the native bigger array that draws hot Frances Salmonella albumen, adds a control reaction, and they are at PCR Express TMExpress on the platform.7 kinds of albumen of this array demonstration are discerned by force by VIG, and wherein 6 kinds is vaccinia virus albumen.In these albumen, 4 kinds (H3L, D8L, A56R and F13L) is the envelope antigen that can be touched by the lip-deep antibody of complete virion.Therefore, the proteic detection in this system has shown height antigen-specific and biology dependency.Unmodified form has extra advantage, and promptly albumen keeps their conformation dependent epi-position probably.

Prepare plasmid from transformation mixture
[0131] transformation mixture that will obtain according to the description of embodiment 2 is originated as the segmental plasmid of the insertion that contains needs, rather than selects single clone to be used for further assessment according to embodiment 2-5.As indicated above, the each conversion is grouped into by following one-tenth: 10 μ l competence DH5 α and 10 μ l DNA mixtures (linear carrier that 40ng PCR-produces, the ORF fragment from vaccinia virus that 10ng PCR-produces; Mol ratio 1: 1, carrier: 1kb ORF fragment).With mixture incubation on ice 45 minutes; Heat shock (42 ℃, 1 minute) was cooled on ice 1 minute; With 250 μ l SOC substratum (2% tryptone, 0.55% yeast extract, 10mM NaCl, 10mM KCl, 10mM MgCl 2, 10mM MgSO 4, 20mM glucose) mix, 37 ℃ of following incubations 1 hour are diluted among the LB (Luria Bertani substratum) that 3ml added 50 μ g kantlex/ml (LB Kan 50), are incubated overnight under the vibration.Separate and plasmid purification from this culture, do not select and do not carry out colony.Substantially translate the plasmid template that obtains according to the description of front embodiment, according to hereinafter transferring to the immunodotting trace.
[0132] prepare the plasmid template that is used for in-vitro transcription/translation with Qiagen micropreparation test kit, comprised " choosing wantonly " step, described step has comprised protein denaturant, to eliminate the RNA enzymic activity.If do not comprise this step, the expression level in in-vitro transcription/translation reaction will be low with inconsistent.Figure 10 uses the PCR fragment from vaccinia virus to show " disruptive gel " (phenol-chloroform cracked bacterium shows total nucleic acid) from overnight culture.Top strap on these gels (direction is towards the right side) is a genomic dna, and two bands in bottom are 23S and 16S ribosome-RNA(rRNA), and the intermediary band is the plasmid by forming with the reorganization of linear carrier and PCR fragment.Comprised in this gel that empty carrier is as reference.In 42 plasmids shown in this figure, only there be 1 (E9L) to lack the insertion fragment of suitable size.In order to calibrate the efficient of overall system, increased, cloned and expressed one group of test cdna that draws hot Frances Salmonella from soil.In 1,933 kind of gene attempting, 96% is successfully increased, and 93% is successfully cloned.
[0133] in 0.2ml PCR 12 empty band pipes, set up in-vitro transcription/translation reaction (available from the RTS 100 intestinal bacteria HY test kits of Roche) with 25 μ l reaction volumes, according to the explanation of manufacturers, 30 ℃ of following incubations 5 hours.Be expressed in one group of 8 vaccination of representative seedling diseases poison and 40 kinds of soil of encoding on the T7 plasmid and draw the proteic albumen of hot Frances Salmonella in based on colibacillary acellular in-vitro transcription/translation system, described system has replenished t7 rna polymerase.With 37 ℃ of following incubations of 25 μ l in-vitro transcription/translation reactions 4 hours, crude product is differentiated on sds page, with anti-polyhistidyl antibody gel is carried out trace and detection (Figure 11).Western blot has shown the expression of product of the histidine mark of predetermined molecular weight.A little less than 3 reactions too in 48 reactions, it is positive to mark.
[0134] for the immunodotting trace, the full RTS of 0.3 μ l volume is reacted artificial point sample on nitrocellulose filter, dry, then with the sealing of 5% skim-milk among the TBS-Tween.Be used in be diluted in the sealing damping fluid that contains or do not contain 10% intestinal bacteria lysate 1/1000 (Canada) vaccinia virus immunoglobulin (Ig) (VIG) is surveyed trace for Winnipeg, Manitoba available from Cangene Corporation.Three crowdes of different VIG have been adopted: lot number 1730204 (56mg/ml), lot number 1730208 (53mg/ml) and lot number 1730302 (56mg/ml).Detect people's antibody by incubation in the anti-people IgA+IgG+IgM of alkaline phosphatase link coupled goat (H+L) second antibody (Jackson ImmunoResearch) and with nitro-BT photographic developer observation.Routinely, also use monoclonal anti polyhistidyl (clone His-1; SigmaH-1029) and mono-clonal rat anti hemagglutinin (clone 3F10; Roche 1867423) antibody, use AP link coupled goat anti-mouse IgG (H+L) (BioRad) or the mouse IgG of the goat Chinese People's Anti-Japanese Military and Political College (H+L) second antibody (Jackson ImmunoResearch) dyeing then respectively, to confirm existing of recombinant protein.For microarray, the Tween 20 of 10 μ l0.125% is mixed (to obtain the final concentration of 0.05%Tween) with 15 μ l RTS reaction, 15 μ l volumes are transferred in 384 orifice plates.With plate 1,600xg is centrifugal, to be settled out all throw outs, uses Omni Grid 100 microarray trace instrument (Gene Machines) with the FAST of supernatant liquor trace to nitrocellulose bag quilt under situation about not being further purified TMSlide glass (Schleicher﹠amp; Schuell Bioscience) on.For all dyeing, at first slide glass is sealed damping fluid (Schleicher﹠amp in protein arrays; Schuell) sealing is 30 minutes in, uses first and second antibody identical with Dot blot (adopting the Cy3 link coupled second antibody available from Jackson) dyeing, scans in laser cofocal scanner.(GSI Lumonics Inc) carries out quantitatively fluorescence intensity with QuantArray software.When adopting full RTS to react on Dot blot and array, VIG has Chinese People's Anti-Japanese Military and Political College's enterobacteria antibody of any antigen-specific reaction of covering of high titre.This is to overcome by the immunoblotting that makes VIG absorption intestinal bacteria lysate or by the intestinal bacteria lysate is added VIG.In preceding a kind of method, intestinal bacteria are dissolved in the SDS PAGE sample buffer, on the preparation gel, differentiate lysate, transfer to Optitran nitrocellulose filter (Schleicher﹠amp then; Schuell) on.Then trace is cut into little (5 * 5mm) sheets, and in 5% skim-milk the sealing 1 hour.Wash described small pieces then, be placed in advance with the sealing damping fluid and be diluted among 1/1000 the VIG, continued to stir down incubation 1 hour.1 liter of intestinal bacteria (DH5) culture stationary phase from be resuspended in 25ml TBS-Tween prepares the intestinal bacteria lysate, with the probe sonication of 2cm diameter.Branch things such as 1ml are stored down at-80 ℃.Lacking the reactive mice serum of endogenous Chinese People's Anti-Japanese Military and Political College enterobacteria does not need to anticipate with intestinal bacteria and reduces background.
[0135] also can on the immunodotting trace, detect non-denatured protein (Figure 12) from not celliferous reaction.Vivoexpression 128 the coding 112 kinds of proteic plasmids of different vaccinia viruss, with each unpurified reaction double point sample of 1 microlitre on nitrocellulose filter.The open reading-frame (ORF) of every kind of gene is designed to comprise N-end 10 * Histidine (HIS) mark and C-terminal hemagglutinin mark (sequence YPYDVPDYA).Also set up the control reaction (' c ') that lacks plasmid template; If the use empty carrier owing to produced little 10 * Histidine positive fragment, has been observed positive signal (data not shown goes out).With anti-HIS traget antibody (Figure 12 A), anti-HA traget antibody (Figure 12 B), vaccinia virus immunoglobulin (Ig) (VIG) (Figure 12 C) or VIG+10% intestinal bacteria lysate (Figure 12 C) detection membrane.Anti-HIS and HA traget antibody do not have other proteic cross reaction in demonstration and the vitro reactions, the therefore conventional expression that is used to monitor big quantitative response.In 112 kinds of different albumen of expressing, only there are 3 kinds all to be negative to HIS (Figure 12 A) and HA (Figure 12 B) mark.In order to assess the overall efficiency of expression, the soil of having expressed 390 kinds of clones draws hot Frances Salmonella gene, will react point sample to nitrocellulose filter, surveys with anti-Histidine or anti-HA antibody.82% reaction is the HA male, and 84% is 10 * polyhistidyl male, the 73%th, and Histidine and HA male, the 7%th, HA and Histidine feminine gender.
[0136] from the trace of Figure 12 C as can be seen, VIG has Chinese People's Anti-Japanese Military and Political College's enterobacteria antibody of high titre, has covered and proteic all reactivities of vaccinia virus.But, in VIG, add intestinal bacteria lysates (Figure 12 D), this background is reduced to can detect the proteic level of vaccinia virus.Positive protein on this trace is A10L, A27L, and D8L, D13L, F13L, H3L and H5R emphasize with redness in title.
[0137] handles serum with the intestinal bacteria lysate and also can effectively reduce intestinal bacteria background response on the microarray.23 vaccination seedling diseases poison and 22 kinds of soil of surveying with the VIG that contains and do not contain the intestinal bacteria lysate draw the flight microarray of hot Frances Salmonella albumen composition to be shown in Figure 13.The effect (shown in the Dot blot of Figure 12 C) of Chinese People's Anti-Japanese Military and Political College's enterobacteria antibody of high titre also is tangible (Figure 13, top array) on microarray.The high background that also exists in the contrast prepared product has been covered the proteic specific reaction of vaccinia virus.Before surveying microarray, add 10% intestinal bacteria lysate, reduced the intestinal bacteria background, shown specific reaction (Figure 13, figure below).This array has shown 5 vaccination seedling diseases toxalbumin by VIG (adding frame), D13L, and D8L, F13L, H3L and H5L discern by force.
[0138] Figure 14 has shown the result of the array of forming from 194 kinds of albumen of the complete vaccinia virus gene group of estimating representative>95%.Personnel selection vaccinia virus immunoglobulin (Ig) (VIG), and the vaccinia virus inoculation of using by oneself is preceding and this array of serum screening of postvaccinal mouse and macaque.Figure 14 A has shown that not contacted antigenic not immune mouse lacks all proteic reactivities that list poised for battle fully, but the antigen-reactive of a subgroup on serum of the mouse that immunity is crossed from vaccinia virus and the array.Different with not contacted antigenic mouse, the antigen-reactive of a subgroup on non-immune people and the array, but with after the vaccinia virus immunity, with the antigen-reactive of another subgroup on the array.The last figure that quantitatively is illustrated in Figure 14 B of data.VIG discerns 26 kinds of different albumen, wherein by also having observed 13 kinds from the serum of the individuality of contacted vaccinia virus not, therefore thinks and represents the non-specific cross-reaction of antibody to other environmental antigens.Remaining 13 kinds is the antigen of the antibodies specific identification that produces in the vaccinia virus immunologic process.In serum, also observed similar collection of illustrative plates (Figure 14 B) from macaque and mouse.Although existence specific specificity is replied (for example, only being A3L or A4L) in mouse, also exist much by the albumen of people and any animal model corecognition with by 10 kinds of albumen (table 1) of all three species identification.These specific antigens will be the preferential material standed fors that is used for the clinical Pretesting of human vaccine.Generally, be the major portion of replying to replying of virus structural protein, described proteic over half all be envelope protein (table 1).Seropositivity albumen comprises having and do not have membrane spaning domain and PI is the albumen of 4-10, and described structural domain has and do not have signal peptide.In addition, reported in the past that some described albumen produced humoral response in animal and human's class, other albumen does not then produce.
[0139] antigen in the table 1 all is the antigen that keeps (WR) strain from the west, but identifies to the title of homologue by them and the nearest straight of vaccinia virus Copenhagen strain herein, because the sign of protein function in this strain is better.Yet, can obtain from the GenBank database from each ORF of WR strain and the sequence of encoded protein, this database can be inquired about from network, and network address is Www.ncbi.nlm.nih.gov/gquery/gquery.fcgiExplanation in the table 1 and the explanation in the database are complementary.The albumen of WR strain and gene order are arranged in vaccinia virus WR genome, can find in GenBank with the gene title of table 1.The blast purposes that employing can obtain by GenBank can easily be identified and above-mentioned sequence and the similar substantially albumen of their corresponding gene sequences.

[0179] carries out pcr amplification with plasmodium falciparum genomic dna template.Because a lot of plasmodium falciparum genes contain intron, have designed the primer of striding each exon.With the big gene (and exon) of pieces amplification above 3000 base pairs, overlapping 150 Nucleotide of each fragment (i.e. 50 amino acid).Cover the genomic design of primers of whole plasmodium falciparum by the genome of UC Irvine and the ArIo Randall of bioinformation institute, can read the primer database by web interface.This database contains 14,446 kinds of entities.Therefore, for each the independently exon and the big gene that amplification exists with the fragment less than 3000 bp of increasing, need 14,446 primers right.But about 40% ORFs coding is less than 50 amino acid whose small peptides, and each ORF greater than 150 Nucleotide that therefore increases needs about 8000 primers right.With the primer sequence source of this online database as following research.
[0180] increases, clones and express 266 ORFs altogether that derive from 218 gene target groups with previously described expression system.Having adopted needs the method that finish in 3 days, from plasmodium falciparum genomic dna pcr amplification 266 ORFs, fragment cloning in the T7 expression vector, is expressed in acellular in-vitro transcription/translation system, with the expressed proteins point sample to micro-array chip.The intestinal bacteria lysate detection chip that the serum of human volunteer of sporozoite immunity of overshoot of being used for hanging oneself is handled makes the slide glass colour developing, usefulness confocal laser micro-array chip reader reading with anti-people's antibody of Cy3 mark.The plasmodium falciparum albumen test of a plasmodium immune body and a subgroup, and not contacted antigenic individuality does not react.Albumen is printed onto on the micro-array chip, uses the serum detection chip from 11 donors, described donor Natural Exposure is in the malaria in Kenya high incidence district, or once with the sporozoite immunity of radiation.Not contacted antigenic donor lacks the reactivity (Fig. 6) to the one group of complete expressing protein that prints on the chip, but from the serum of the individuality of immunity and the subgroup albumen test on the chip.These results' general introduction is shown in table 4." locus " code representative in the table 4 is corresponding to " locus label " code that uses in the GenBank database, and this database can onlinely obtain, and network address is www.ncbi.nlm.nih.gov/gquery/gquery.fcgi.Therefore, can be easily obtain in the table every kind of proteic dna sequence dna and peptide sequence with these codes.
[0181] from this Analysis and Identification 9 kinds of strong reactive proteins.In the proteins C reactive 7 kinds of 9 kinds of height are Pf blood stage antigens known, abundant sign, wherein much carrying out clinical development and assessment (LSA3, MSP4, EBA175, RESA).What is interesting is, PF10_0356, promptly stage antigens 1 is a phase specific antigens in the liver in the liver; It is not expressed in the sporozoite or the blood phase of biology, and only the phase expresses in liver.Therefore, 6 parts of these antigenic facts of serum identification in 11 parts of serum have proved that the protein groups array has the ability of not only identifying the blood stage antigens.Equally, PFD0310w is SHEBA/Pfsl6, promptly a kind of sexual stage antigens that is carrying out clinical development as the vaccine antigen material standed for.Have one of antigen of strong reactivity, i.e. PFE1590w, not being realized in the past is possible vaccine antigen material standed for.
